I heard about some inexpensive security cameras which get their power through the same cat5 cable which delivers the data/pictures (which would simplify wiring tremendously). Does anyone know about these? Do they work with Linux, particularly CentOS?
tnx 4 tips.
Not sure it will answer your question but there was an article in December 2010 issue of Linux Magazine re surveillance cameras and linux.

BJ, I looked around Linux Mag's site for quite a while, did a couple searches, and browsed the contents Dec 2010 and quite a few issues before and after that, but couldn't find any article about selecting and/or setting up surveillance cameras... except one on implementing motion detection in cameras. Is that the one you were thinking of?
Still, thanks much. I'll probably come back to that one later. If some other info source comes to you, I'd be glad to hear about it.

Sorry about that. I cannot find the article on their website. Page 30 in the paper version by Marcel Gagne. Did have some stuff on motion detection but article was broader than that and the links at the end of the article might be useful, especially this one:

Good luck.

TCP/IP cameras would work with any OS, most just FTP or whatever the pictures to a webserver you provide, or they run their own server and you can wget the pics off them. but I've never seen any IP cameras I'd call really cheap. Panasonic makes a nice line of them, some even have remote pan/zoom via a http interface.

Try Ebay especially the Chinese, including Hong Kong, suppliers. For example compared to the English prices the Chinese prices are much cheaper. However one has to wait 2 to 3 weeks for postal delivery.
Delivery to the USA is usually quicker than to England. The Chinese preferred payment currency is USD.

Been there, done that. You're often much better off with known brands, like Logitech, for simple webcams on your existing server. I've used this effectively for rack security in a datacenter: as long as you're not polling the webcams constantly, they're not too bad of a bandwidth pig, either. They've been around long enough to be stable and workable in Linux, as well.
If you want a full-blown remote TCP monitoring system, look at Axis. They're historically very Linux compatible, they have all the features you might want, and while they're not cheap they have all the features you might need.
Check bluecherry.net
I've have for Topica cameras running for over three years. No problems and good people to deal with.

At work, we use the package motion. Does everything, including writing .avi? .asf? files to the home directory which is nsf mounted. Trivial load on the network for monitoring.
We've got *really* cheap old webcams. Do see if you can get USB 1.1, not 1.0....

I've been following this thread closely, and am interested in setting up some surveillance in the office using Linux as well.
What open source software can I use for large streams, like upto 256 on Linux? We currently use Indigo, which is super expensive and runs on Windows.

Yeah, I know that one. I wrote some of the early RPM's for it. It had integration issues way back at RedHat 6.2, but has improved a lot since then.
Amusingly, someone I worked with was insisting, *insisting* that anything that came out in newer kernels, they could backport to their modified 2.0.x optimized kernel, because *of course* their patches were so clever and so important that they could never be ported forward, a newer kernel could never hope to match it. But good USB and webcam support was only workable in the 2.2. kernels, backporting it to 2.0 was ridiculously infeasible. And the "upgrade versus backport war" was on!!!
We seeing the same things with new features in RHEL/CentOS releases, such as Samba features and OpenSSH major releases and Bind.

I've been meaning to try ZoneMinder (www.zoneminder.com) for some time but have not just yet. In any case there is some good info on cameras in a few places on that site, "Hardware Compatibility List" section of the forum for one.

I have a security camera, though not powered through the cat5, will have to check that out... Anyway, I'd recommend these sites:
http://www.zoneminder.com/ http://www.cctvcamerapros.com/
Right now I have my camera attached to an RF modulator and splitter which merges the signal onto the coax run on channel 65 so I can watch it on my TV. As far as integrating with Linux, would check out Zone Minder link above, otherwise if you modulate onto your TV stream like I did you can then just use mythtv or any capture program if you wanted to schedule captures, etc.
Have fun,
Josh

AFAIK there are different options you can take with this.
Webcam USB camera or a PAL/NTS CCTV camera with a phono or BNC connector.
Use a PCI based video capture card to connect CCTV cameras to. Not sure about the software to use though.
Use a stand alone DVR - digital Video recorder to capture and record sound/video, as well as simultaneous monitor and IP broadcast over the net. Some of these boxes run Linux and an integral web server. You can also manage and control the DVR across the net.
You might find these links helpfull:
http://www.henrys.co.uk/cctv.htm http://en.wikipedia.org/wiki/Digital_Video_Recorders
I think you will get far better video quality using CCTV cameras than a webcam on a USB port.

you may think that, but those solutions you mentioned are all NTSC composite video, while even a $30 USB webcam now days is 2 megapixels or higher.
anyways, the OP wants cameras that connect to the network and get their power off the ethernet cable, not a USB or a CCTV camera.

Trendnet has some. You'd need to get the java plugin working to view them in a linux browser - not sure about full-time recording software. If you don't have enough to justify a POE switch, you can get individual power bricks that plug into the line to add power at a convenient place.

Les, thanks for the pointer to Trendnet. They've got a *large* selection.
I'm finding that there's a variety of video formats output by these various devices... which is a consideration for us non-Windows folks. I haven't come down to a decision on which yet. Of course it's going to depend upon which are supported by Linux. For some reason, on my system flashplayer is unreliable... sometimes it works, sometimes not. MPEG4 though works fine in Firefox. Due to past experience (many bad ones), I'm leery of Java-based software, so I'd be shy about using that plug-in. Hopefully there'd be other alternatives... anyone know about some?
Les, you bring up a good question about full-time recording. I don't know at all how that might work on Linux. Someone earlier mentioned ftp'ing the video files. If that's all it takes, then great. Some of the IP cameras have an ftp client, but I haven't seen one yet with an ftp *server* on it, so how it's possible to fetch and save the video files is still a mystery to me. Anyone with experience doing this with Linux?
Thanks to everyone for the comments and tips, the previous and future ones.
Best, ken

Hello, We have had success ACTi cameras http://www.acti.com/home/index.asp and use ZoneMinder as a DVR and a console for viewing cameras http://www.zoneminder.com/ We have also used Axis cameras but the ACTi cameras are less expensive and better fit the schools budget.

Don't take this as a recommendation, but I did just get an email ad from buy.com with what looked like some good prices.

The older trendnet ones we have offer active X or java as viewing choices in the browser. They'll capture images but just as snapshots, not video.

If you need that, it might be better to get a bundled standalone system that includes the recording hardware.

If you Google for "ip cctv" or "ip cctv forum" or "ip cctv camera review" there will be tons of results returned :)
One of the dedicated ip cctv forums may be a good place to actually get more detailed advice on this topic.

Yes. True. I'm not interested in either USB or CCTV. Ethernet cams are much better and smarter technology and, from what I hear, easier to install and set up.
